9 . 阅读以下材料并回答问题:
①单位根与本原单位根:在复数域,对于正整数
,满足
的所有复数
称为
次单位根,其中,满足对任意小于
的正整数
,都有
,则称这种复数为
次本原单位根.例如,
时,存在四个4次单位根
,
,因为
,
,因此只有两个4次本原单位根
;
②分圆多项式:对于正整数
,设
次本原单位根为
,则多项式
称为
次分圆多项式,记为
;例如
;
回答以下问题:
(1)直接写出6次单位根,并指出哪些为6次本原单位根(无需证明);
(2)求出
,并计算
,由此猜想
的结果,(将结果表示为
的形式)(猜想无需证明);
(3)设所有12次本原单位根在复平面上对应的点为
,两个4次本原单位根在复平面上对应的点为
,复平面上一点
所对应的复数
满足
,求
的取值范围.
